With the approach of the 3rd season of My Little Pony: Friendship is Magic, I thought about the possibility of a new villain coming in to start off the season like Discord did in season 2, and this got me thinking about what kind of villain I'd absolutely love to have in an episode(s) of MLP, despite the impossibilities of it happening.
Now, I'd like to know what your dream villain would be for MLP. You can include a creature/pony, some backstory for this character, and a voice actor whom you'd like to portray your villain (even if he/she is currently deceased).
For example, my dream villain would be an elder unicorn who sees himself and all other unicorns as the superior race of pony and wants to enslave pegasi and earth ponies alike. I'd want him voiced by Tony Jay, who you most likely know as the voice actor who played Judge Claude Frollo in Disney's Hunchback of Notre Dame.
What would you have in mind? I'm interested to know.
